Calibration & the Test Jack 

 

Calibration 

Warning  

Do not remove the cover when the instrument is powered unless 

the area is known to be non-hazardous. 

  

1.

 

Make all pneumatic connections, and plug all unused ports.  

2.

 

Provide a supply pressure. 

3.

 

Connect a high accuracy pressure indicator to the output port.  

4.

 

Connect a current source to the positive and negative terminals of the 
terminal block.  

5.

 

Input 0% of the calibrated range, and adjust the zero for 0% of desired 
output. 

6.

 

Input 100% of the calibrated range, and adjust the span for 100% of 
desired output. 

7.

 

Repeat steps 5 and 6 until no further adjustments are necessary. 

 

The Test Jack 

 
Note  

Inserting the test jack without connecting a calibrator or ammeter 

will interrupt the loop power signal. 

  

1.

 

Refer to 

Figure 5–1

 and connect a current calibrator to the jack plug 

cable as shown.

2.

 

Insert the jack plug cable into the test jack. The current calibrator is 
now the input signal source.
